Help! My game disapeared! Thread

I think either I'm dealing with some sort of cookie bug, or maybe I've been hacked?

But I updated some information for my game, went to go edit a video for an update article -and when I came back after about 30 minutes to an hour, It was gone.

I had to stop working on it because my motherboard fried out and I couldn't afford to get a new one until recently. I don't have those videos or the articles anymore, I really wanted to keep log of the development. Seriously. Please help.

I think maybe I cursed? If i did, please, I'll fix that. I just didn't see a warning or anything, I honestly just didn't think about it.

Please I've been working on this game for over a year. I don't want to lose all of those screenshots, videos, and my articles.
